For starters you need a smoke muffler. The stock muffler that comes with the 91 wont work. What you were doing is just dumping smoke oil into the muffler and some prob was getting into the motor making it quit. The nipple on the muffler was just for pressure for the fuel system.

A smoke muffler has coils inside that preheat the smoke oil then dumps it into the hot muffler where it smokes. I have seen some articles in mags for homemade preheating systems, but seems like too much work. Best thing to do is go out and look for a smoke muffler.

You got smoke on the ground because the muffler was hot and if you would of waited the smoke would of quit even on the ground.
